I'm probably about 95% convinced of the flat earth under a firmament dome and perhaps it's inside a globe like DL's pictures.
(Thanks for posting those again, DL. They are very helpful!)
As a kid I could never understand how water could curve and stick on a ball and how we didn't feel the spin at a 1000 miles an hour and how centrifugal force wouldn't make water and other things fly off.
But who am I to judge?

I've always just been one of those annoying people who ask annoying questions about things other people don't really want to bother with.

Then in the 90's I worked as a flight attendant and I started asking the pilots questions like:
Why are we flying over the northern arctic when it's way out of the way and we have to watch every penny of fuel costs which are so high? Fuel costs were a constant concern in the volitile Airline industry because if they went up just a few cents it had a major impact on the bottom line and caused several airlines to go under. Also, I wondered why other people didn't ask about us flying off course and maybe get concerned that we were being hijacked or something else was wrong, but people just go along...
Since I was a kid I always wanted to see water curve because I couldn't imagine how it works. I was so excited to finally get to see the view in a large window of the cockpit of a 747 at 30,000 feet above the Pacific. Finally I'll get to see water curve! Nope....The horizon for 100's of miles was perfectly level. Flat! I asked where the curve was and the pilots told me it was there, can't you see it? Ugh...I hate gaslighting.
I asked some pilots while we were waiting for our plane one day why the spin of the earth didn't drastically change our flying time from east to west and why we don't circuмnavigate the globe north to south. They said the atmosphere keeps us from the effects of the spin (which didn't make sense to me) and somebody I never heard of in school or on TV had circuмnavigated the globe north to south. Strange we never hear about it since it's such a big deal and strange we don't have any flight routes that make use of this short cut under the globe.
When I asked if the plane had to make adjustments nose downward as we go over the curve so we don't fly out into space they admitted that no it doesn't make any adjustments nose downward. I knew we would feel the nose downward movement since even a slight adjustment to the level of the plane port, starboard or aft is very noticeable in the cabin and you never feel the plane go nose down even a slight amount. So since we don't make adjustments how do we keep from flying straight into space??
The First Officer smirked and blurted out, "I guess you'll have to be a Freemason to know about that."
"What?? What's a Freemason? Those guys in lodges?" I asked.
The Captain gave the FO a dirty look and got all mad and started demanding of me, "Are you some kind of Flat Earther?"
Me (perplexed at what made him so mad): No.
Captain: Well you sure sound like a Flat Earther!
Me: No...I'm just a person asking questions.
Captain: Well are you sure?
Me: Why? Can't I ask questions?
Captain: Well, I just want to know if you're one of them because you sure sound like one!
Me (getting even more curious now because of his bizarre emotional reaction but not wanting to rock the boat further): Nope.
Captain: Well okay then.
And they walked off...
There was no internet to go and research Flat Earth so I let it be for a number of years but I felt so alone...like why wasn't anybody else asking what seemed to me like very obvious questions???
Then years later I had a friend with a backyard telescope and got to see a good view of Venus and it didn't look anything like what NASA told us. It was moving about like a plasma ball with it's own light. It didn't look like anything with solid land. Nobody else seemed to notice the discrepancy or question it and when I asked friends and family about it they shrugged it off which again seemed so bizarre to me because it really bothered me.
Then I once saw a sunset over the Pacific and mentioned to my husband how strange it was that it never actually set. The sun got smaller and smaller in the distance until it disappeared but never appeared to go down "behind" the earth. ??
Now with the Nikon P900 cameras people are seeing boats that should be hidden down under the curve and it's getting pretty obvious to me.
Then you find all the Biblical references for the firmament. How do globe earthers reconcile that? Can the globe with expanding space have a firmament? Is the firmament just an old fashioned notion?
I think one of the reasons it's so hard to break through the brain fog programming was demonstrated by the Asche conformity experiment:
1min 57sec
It's very hard to go against the crowd and globe earth peer pressure is enormous! Making fun of flat earthers asking very reasonable questions seems to be a universal modus operandi and it's very powerful. It's like the Emperor's New Clothes. Of course you can see his clothes can't you???

It's lonely to dissent.

Isn't that strange? If you "question the science" you get made fun of?? What else is like that? Question evolution, covid shots, moon landing and you'll get made fun of. Very powerful!
Anyway, I would be happy to believe in globe earth if somebody could provide me with one picture of buildings leaning as they go over the curve.
I can't find one. A ship will allegedly "disappear down under the curve" 6miles out to sea but I have never seen a skyline that shows buildings starting to lean over even just a little. A three foot drop causes the Leaning Tower of Pisa so it's very visible to the naked eye. No equipment necessary. According to globe math a 3 mile skyline should have a 6 foot drop!
Challenge to Globe Earth believers: Please provide me with a photo of this phenomenon and I will happily convert. :)
I'll start another thread with my challenge and see what we can find...
